Primary Thyroid Lymphoma: A Rare Diagnosis Treated With Polatuzumab Vedotin.

Primary thyroid lymphoma is one of the rare and distinct type of extra nodal lymphomas originating within the thyroid gland. It accounts for less than 5% of all thyroid malignancies and 2% of extra nodal lymphomas. It predominantly affects older adults, with a higher incidence in women. Patients typically present with a rapidly enlarging thyroid mass, accompanied by clinical symptoms of compression such as dysphagia, dyspnea, and hoarseness. Diagnosis is established through a combination of fine-needle aspiration, core needle biopsy, and advanced imaging techniques. Standard treatment involves a multimodal strategy of chemotherapy, often with the addition of radiotherapy and surgical intervention. Herein presented is the first reported case of diffuse large B-cell lymphoma treated with Pola-R-CHP. [ABSTRACT FROM AUTHOR]
